CREAMERY BUTTER MAKISG 163 



The walls of the refrigerator are buih in the same way 

 except that the inside is finished with cement as already 

 mentioned. 



CREAMERY ROOE. 



It matters not whether the creamery is constructed 

 of wood or brick, a shingle roof is undesirable because 

 of the danger from fire. Twenty-six gage galvanized 

 iron, when properly laid, will make a cheap and very 

 durable roof. The roofing should be laid with stand- 

 ing seams to allow for expansion and contraction of 

 the material. To protect the under side of the roof 

 from moisture and corroding gases it is desirable to lay 

 the galvanized iron on common building paper. 



Slate makes the neatest and most durable roof but it is 

 rather expensive. 



HEATING OF CREAMERY. 



Creameries should be heated with steam, not with 

 stoves. Either the exhaust steam from the engine or 

 steam taken directly from the boiler may be used for 

 this purpose. The heating pipes should be so arranged 

 that either may be used when desired. 



Where the exhaust steam is used to heat water for the 

 boiler and for washing, it may be best to heat the build- 

 ing with steam taken directly from the boiler. 



A very satisfactory method of piping is the following : 

 Run one and a half inch pipes from the boiler to within 

 two feet of the floor, and close to the walls, of the 

 creamery room. The pipes should pass all around the 

 creamery room and end in a steam trap which discharges 

 the condensed steam into a hot well located near the
